Answer:
some of the weak-acid component of the buffer will dissociate and turn into the conjugate base (which is the weak-base component of the buffer) thus replenishing most of the protons removed.
I think the answer is D, because the DNA wraps around proteins called histones to form chromatid.
The experimental results are considered to be statistically significantly different from the expected outcome.
In order for a result to be considered statistically significant, an analyst must conclude that it cannot be solely attributed to chance. The analyst reaches this conclusion via statistical hypothesis testing. It is employed to offer support for the null hypothesis, which contends that the data are merely the product of random chance, to show that the null hypothesis is plausible.
With the assumption that the results are actually of pure chance, this test yields a p-value, which is the likelihood of seeing outcomes as extreme as those in the data. It is frequently accepted that a p-value of 5% or less indicates statistical significance. The p-value for the discrepancy between the observed experimental results and the expected result in the particular scenario is less than 5% (p 0.05). It is therefore statistically significant.

Answer:
Option (1).
Explanation:
Action potential may be defined as the change in the cell potential that helps in the transmission of the nerve impulse. The resting membrane potential of the cell is -70mV.
The depolarization phase of the cell has membrane potential towards more positive. After the depolarization phase, the sodium channels are closed and potassium influx occurs that causes the re-polarization of the cell. This activity of the re-polarization is not the consequence of the closing of the inactivation gates.
Thus, the correct answer is option (1).
Answer:
c. 3, 5, 1, 4, 2
Explanation:
1. (3) food substance dissolves in saliva
2. (5) food substance enters taste pore and attaches to receptor on gustatory hair
3. (1) gustatory cell depolarizes
4. (4) neurotransmitter released by gustatory cell
5. (2) action potential stimulated in gustatory neurons
<em>Saliva has digestive functions that help food to be easily swallowed. We need saliva to taste foods because it dissolves the chemicals. The sense of taste is called gustation. We taste something with our tongue and then sensations would be carried via the facial (VII) cranial nerve. One of the newest taste to be described is umami. </em>
